Angelonia plant named ‘Cas Lavener’

ABSTRACT

A new  Angelonia  plant named ‘Cas Lavener’, articularly distinguished by the purple-violet flower color, slightly upright and semi-trailing habit with dense foliage and branching, exceptional heat tolerance, and good vigor.

Latin name of genus and species of the plant claimed: Angeloniaangustifolia.

Varietal denomination: ‘Cas Lavener’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Angelonia, botanically known asAngelonia angustifolia, and hereinafter referred to by the variety name‘Cas Lavener’.

‘Cas Lavener’ is a product of a planned breeding program. The newcultivar ‘Cas Lavener’ has a purple-violet flower color, slightlyupright and semi-trailing habit with dense foliage and branching,exceptional heat tolerance, and good vigor.

‘Cas Lavener’ originated from a hybridization in a controlled breedingprogram in Gilroy, Calif. USA. The female parent was an unpatentedhybrid seedling identified as ‘432-1’ with a lavender and white color.‘432-1’ has fewer branches and darker and larger foliage than ‘CasLavener’.

The male parent of ‘Cas Lavener’ was an unpatented hybrid seedlingidentified as ‘421-3’ with a deep lavender color. ‘421-3’ has smallerflowers, fewer branches, and is more prostrate than ‘Cas Lavener’.

‘Cas Lavener’ was selected as one flowering plant within the progeny ofthe stated cross in 2006 in a controlled environment in Gilroy, Calif.USA. The pollination took place in September 2003 and the seed sowing inMarch 2006 all in a controlled environment in Gilroy, Calif., USA.

The first act of asexual reproduction of ‘Cas Lavener’ was accomplishedusing vegetative cuttings from the initial selection in June 2006 in acontrolled environment in Gilroy, Calif. USA.

Horticultural examination of plants grown from cuttings of the plantinitiated in June 2006 in Gilroy, Calif. USA, and continuing thereafter,has demonstrated that the combination of characteristics as hereindisclosed for ‘Cas Lavener’ are firmly fixed and are retained throughsuccessive generations of asexual reproduction.

‘Cas Lavener’ has not been observed under all possible environmentalconditions. The phenotype may vary significantly with variations inenvironment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar was applied for in Canada onDec. 24, 2007 (PBR 07-6080). ‘Cas Lavener’ has not been made publiclyavailable more than one year prior to the filing of this application.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawing shows typical flower and foliagecharacteristics of ‘Cas Lavener’ with colors being as true as possiblewith an illustration of this type. The photographic drawing shows acontainer consisting of 3 flowering potted plants of the new variety anda close-up of the flower. Both photographs were taken in the spring of2008 in Gilroy, Calif., USA. Both were grown in Gilroy, Calif., USA andwere approximately 3–4 months old.

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Gilroy, Calif. USA, in April 2008 onplants that were growing in gallon pots in a greenhouse. Culture ofthese plants started about January 2008. These plants are about 3 monthsold.

Color Chart used: Royal Horticultural Society Colour Chart (R.H.S.)2001.

BRIEF SUMMARY OF INVENTION

The following observations, measurements, and comparisons describeplants grown outside in Gilroy, Calif. USA. The following traits havebeen repeatedly observed and are determined to be basic characteristicsof the new variety. The combination of these characteristicsdistinguishes this Angelonia as a new and distinct variety.
